The Audi Quattro was a groundbreaking vehicle in this form of motorsport when it was the first rally car to use all-wheel-drive. This 1985 Audi Sport Quattro S1 (above) was a World Rally Champion runner up back in the day.

And, waving the American flag are two Fords. The first being a 1986 RS200 Evolution (above), of which only 24 were built, along with a standard 1985 RS200, which no doubt will be more affordable, being one of 200 produced.

The rally legends will go to auction with Bonhams in California on August 18.
